They were caught in the act by someone passing by who reported what they saw to police who later recovered all the texts, images and videos they compiled of sexually assaulting a toddler.

The good samaritan also provided police with evidence of Diaz and Leon sexually assaulting the toddler while engaging in sexual relations with each other while the toddler was asleep.

Police learned that Diaz gave the child sleeping medication.

In Court, Diaz plead guilty to two counts of first degree aggravated sexual assault and one count of endangering the welfare of a child by causing or permitting a child to be portrayed in a sexually suggestive manner and filming it.

Under the terms of her plea agreement, on the charge of endangering the welfare of a child, Diaz faces 10 years in state prison, subject to an 85 percent period of parole ineligibility pursuant to the No Early Release Act.

"The plea agreement further recommends a consecutive 25 years New Jersey state prison with a mandatory 25-year period of parole ineligibility on the aggravated sexual assault charges pursuant to the Jessica Lunsford Act.

Additionally, Diaz will be subject to the requirements of Megan’s Law registration and Parole Supervision for Life upon release from prison.

Diaz now faces up to 35 years in a New Jersey state prison, with a period of 33½ years to be served without the possibility of parole when she returns for sentencing on July 23, 2021."

Leon was sentenced in 2019 to 25 years in state prison for first degree aggravated sexual assault and second degree possession of child pornography.

The case was prosecuted by Monmouth County Assistant Prosecutors Tara Wilson and Julia Alonso.

Diaz is represented by Al Kapin, Esq., of West Orange.
